DEVICE FOR PERFOBATING MUSIC-ROLLS FOR SELF-ELAYlNG PIANO irritations."

T0 (d6 whom, it nay concern.-

Be it known that I, ADOLF ROTHERMU'NDT,

a subject of the Czar of Russia, residing at Dresden-Blasewitz, Germany,have invented a cert am new and useful Device for PerforatingMusic-Rolls for Self- Playing Piano At tachments, of. which thefollowing is a specification. Y 1

The present invention has reference to a device for stamping out theholes and slots in sideview; Fig. 3,a front view; and F10. 4, a;

cross-section through the device, the Tatter figure on an enlarged scaleand being partly broken away.

The cutting-out or punching device roper is mounted on a carria etraveling si ewise,

while the music-band c amped in a frame is caused to travel to and frorectangularly to and below the carriage. The music-band a, consisting oftough paper or fabric, is unwound from' the supply-rollerc, held by theclamping device I), is then conducted between the sides of themachinefr'a'm'e d df, and is finally wound upon the roller e.

sary tension is given the band by means of two felt-lined clampingdevices f and g, which at the same time form the short sides of the IThe one side-partd carries a removable scale for measuring thetimemeasures on the music-band. The to-and-- fro movement of the frame dg d f onthe pedestal s is obtainedby means of a rack-andpinion gearingm, actuated by the handwh'eel Z. The traveling carriage k carries thepunching devices and can be shifted by hand from side'to sideindependently of the frame movement. Y

The stamping device proper is shown on a somewhat enlarged scale in Fig.4 and con: sists of a number of punches n p, ordinarilyheld in theinoperative position by the helical s rings 4). to pil ars t, serve todepress the punches. To the front of the device are secured a number offingers g, each one of which corresponds to Specification of LettersPatent. Application filed July 20,1905. Serial No. 270,535.

The neces v Hand-levers o, pivoted at w l I Patented iiune 1906 one ofthe punches and extends above a blind keyboard 't, rigidly secured tothe pedestal s.

The cutting-faces of the punches are such that from left to rightthe'first unch will stamp out of the paper strip a ho e of about threethirty-seconds of an inch in diameter,

while the succeeding unches will stamp out slots,thein creasing l engthsof which correspond to the respective note value,

The operation of the described parts is as follows: If it is desired,for instance, to cut outa'one-fourth-time note, the carriage 7c is Ishifted untilthe finger q,'c'orresponding to the one-fourth-time-notepunch points to the key.on the blind keyboard corresponding to the-pitchof the note to be unch.ed. The lever 0, and' by it-that punc isdepressed, the cutting length of which corresponds to a one-fourth note,and a slot of this length is cut out of the paper stri If an accord isto be taken down, the ot er composing notes are cut out in similarmanner on shifting of a the carriage'after each note. For advancing tothe next measure the frame (2 g d f is advanced by actuating thehand-wheel l, the exact extent of displacement being read-off on thescale'h. After in this manner several measures have beenstamped out amark 13 made on the paper bandfor instance, a pencil-lineat thepointindicated by the indicator r, rigidly secured to the pedestal s.

'The frame d g d f is then rearwardly displaced by turning thehand-wheel Z. The clamping devices f and g are eased, and the punchedpart of the music-band is WOUIId upon the roller until the pencil-markcoincides again with the indicator r. The clamping devices f and g arenow tightened again and the punching operations repeated, as abovedescribed.

What I claim as new, and desire to secure by Letters Patent, is- I 4 1.In a device for perforating music-rolls for self-playing pianoattachments, the combination of a pedestal, a frame traveling on saidpedestal, means for traveling said frame, rollers and clamping devicesfor the music-band -at either end of-said' traveling frame, a graduatedscale on said frame, an indicator and a blind keyboard on said pedestal,a carriage traveling on said pedestal rectangularly to and abovesaidtraveling frame,

keyboard, the various parts being construct- -slmet-carriage, a blindkeyboard thereon, a

punell-carriage, punches on the punch-earriage, and means for bringingone of the punches into line with a selected key of the blind lieylmardto perforate the sheet.

3. in a device of the character described, a reciprocating carriage,ablind keyboard thereon, a puneli-carriage movable transrersely of thesheet-carriage, punches thereon, and means for bringing a selected punchinto a relative position to a selected key of the keyboard forperforating the sheet of the sheet-carriage;

4. In adevice of the character described, a

' transversely of the sheet-carriage, punches of dili'erent punchingarea on the punch-carriage, means 'lor bringing a selected punch into arelative position to a selected key of the keyboard for perforating thesheet con tained in the carriage, means for moving the sheet andsheet-carriage simultaneously, and means for movingthesheetindependently of the sheet-carriage. I i

In testimony that I claim the foregoing as my invention 1 have signed inname in presence of two subscribing Witnesses.
